dc.description.abstract The present survey searches for the inhibitory power of germination and the growth of the seeds of the barley (Hordeum vulgare); the effect antimicrobial of the excerpt aqueous foliaire and of seed of Pergularia tomentosa L. (Asclepiadaceae) harvested in the region of El Meniaa (northern Sahara is Algerian). He is noted that the tested excerpts foliaires presents an inhibitory power of the exceptional germination; a rate of inhibition of 100% is recorded for the shares treated by the concentrated excerpt. In the same way, he/it noted that these preparations present a strong power antimicrobial, of zones them of inhibition of 10,0 mm on the mushroom Candida albicans; of 12,0 mm on Penicillium spp of the excerpt foliaire; for the excerpt of seed the zones of inhibition of 11,0 mm are observed on the Candida albicans mushroom; and of the zones of inhibition of 11, 33mm,; on Penicillium Sp. For the bacterium extracted aqueous foliaire of the zones of inhibition of 11,00 mm on Escherichia coli and 11,00 mm on Staphylococcus Sp. ; For the excerpt of seed the zones of inhibition observe 10,67 mm bacterium Escherichia coli ; and of 10 mm on Staphylococcus sp. The excerpt foliaire of Pergularia tomentosa possesses the properties phytotoxiques and exceptional antimicrobial. EN_en
